Both POSIX and glibc use 'restrict' in strtok(), strtok_r().
Let's use it here too.

.../glibc$ grep_glibc_prototype strtok
string/string.h:340:
extern char *strtok (char *__restrict __s, const char *__restrict __delim)
     __THROW __nonnull ((2));
.../glibc$ grep_glibc_prototype strtok_r
string/string.h:350:
extern char *strtok_r (char *__restrict __s, const char *__restrict __delim,
		       char **__restrict __save_ptr)
     __THROW __nonnull ((2, 3));
.../glibc$
